To all u /tom it may concern:

Be it known that LXVI LIAM O. ALDRICH, a citizenofthellnited States, residing at Whitinsville} county of lVorcester, and State of lvl'assachusettahave invented certain new and useful Improvements in Boving-(lreels, of which thefollOWing is a full and true specification, such as will enable others skilled in the art to make, construct, and use the same. v i

The invention isan improvementin roving creels forspinning and doubling frames, with the object to improve the durability and usefulness thereof, and consists in a sheet metal constructionof such apparatus, and in the combination, relative arrangement and construction of ,the several parts thereof whereby certainnew nd improved results are obtained, as, hereinafter fully described. w a Referring to the drawings, Figure. 1 is a vertical transverse section of a roving creel of a spinning frame embodying the invention; Fig. 2 is aside elevation of the same mechanism with parts removed for clearness; Fig. 3 is a surface plan of a. portion of the middle creel-board Q11 enlargedscale; Fig. l: is a section of Fig. 3 on line a.c; thereof; Fig. 4: is a similar view, of amodified form of board; Figs. 5 and Gare re spectively top plan and vertical section of a modified form of skewer bearinggFigs. 7 and 8 are similar views respectively of a further form of skewer bearing; andFigs. 9 and 10 are similar, views, respectively, of a top holder according to thisinvention,

Referring to Figs. 1 and 2,.the creel taken for illustration is a two-story creel comprising a base or bottom board 1, a middle board 2, and a top boardB; The bottomcreeh board is suppprted onthe cross-braces 4,-

which unite the roller beams 5, and is formed of sheet-metal, preferably in asingle plate, with the central longitudinal area thereof pressed or bent upwardly forming a. central table somewhat elevated above the naein of said b a d andabo h level of the roller beams. The top, and

middle creel boards are carried'gby inter? med ate uprlghts fi and'end uprights ,7

mounted onthe central tableportion ofthe bottom board and are made of-sheet metal which is preferably formed of a piece vr ch ea d that is tasty of an? Plate 1 Specification of Letters Patent.

. i pii at mea S rtei b 9,. le s. Seria N 25 in thetransverse direction, and each plate isformed with marginal reinforcing flanges. In ,thecase offthe middle board, the reinforcing fianges, shown, at 2 are turned downwardly, for convenience of access to the upper row of bobbins, and theflanges of the top board are turned upwardly, as

shown at 3%, to form a trough or receptacle for extra skewers or bobbins. The ends of the top and middle creel-boards are supported on theadjustable sectionsof the end uprights? while their intermediate portions are secured to'the sliding sleeve brackets on the intermediate uprights 6, which arrangement permits verticaladjustment of thetwo upper boards in obvious manner in conformity with theheight of the bobbin skewersof each story of the creel. The flanges on the two upper creel-boards and the upwardly pressed table portion of the bottom board respectively serve to stiffen these members against; the effect of vibration and adapt them to carry the load of the bobbins without sagging and likewise provide rounded edges to the creel boards which safeguard the heavy bobbinsfrom injury by contact with them, It is also advisable to press or form corrugations in the creelboards, as shown for example in Fight wherein the corrugations are longitudinally 'disposed'aboutmidway between the center and the marginal flanges,all of which re inforcement permits relatively thin material to be employed for the creel-board plates, which is desirable for the fullest realization of the benefits of the invention. The severalcreel boards are punched with a plu-' rality of perforations 9 (see'Fig. 3) some of which are adapted for receiving the step bearings ofthe skewers and others of which serve tosecure the holders for the tops of the skewers, and the arrangement of the steps and the top holders is such that no two bobbins on the same side ofthe frame occupy the, samevertical transverse plane.

The skewer steps of the form of the 111- vention shown in Fig. l are pressed into their gppl'opriate holes as indicated at 10 andheld f-rictionally therein in a position in which their. lower ends project somewhat bel w h ott m of t e b a o hat they are acc ibl f m Y th un er t er name are Figs- "au ew -step 1} s t med withja heaclflang 12 which tion or other cause.

supports the step by resting on the margin of the creel-board perforation 9, the lower extremity of the body of the step projecting downwardly beneath the bottom surfaceof the creel-board. A spring washer 13 provided with inwardly pointed spring fin. gers 18, embraces the projecting extremity of the step, engaging a slight ridge or base flange thereof, and forms releasablemeans for locking the step against accidental dis placement from its hole. In the form of Figs. 7 and 8 the skewer-step 14 is provided with a similar head flange, and a split of the creel-board, so that they do not form receptacles for dirt, nor oppose the free passage of the wiping brush. And in each case'it will be noted, the skewer-step projects through the perforation in the relatively thin material of the creel board and depends considerably below the bottom surface thereof, which arrangement permits the ready removal of any step when worn or broken, by simply pushing on it with the finger or by driving it upwardly with an appropriate instrument from underneath. At the same time, andparticularly in the cases of Figs. 6 and 8, the steps are secured against accidental displacement from vibra- These skewer-steps as shown in the drawing are usually niade'of porcelain, glass or similar vitreous and hence easily frangible material. For this reason they are required to fit their perforations in the sheet metal plate with some 7 looseness to keep them from becoming broken by the'expansion of the sheet metal or their own expansion under changes of temperature. .The spring securing rings engaging with their projecting bottoms, hold the steps as thus mounted, from accidental dislodgment without exerting injurious pressure upon them.

The skewersS bearing their bobbins B are vertically seated in the skewer-steps constructed and mounted as above described,

' and as shown in Figs. 1 and 2, andjthe upper extremities of the said skewers are supported within top holders which project from the under side of the upper boards.

virtccording to my invention these holders are hollow thimbles secured within certain of the perforations inthe upper creel-boards and project downwardly therefrom fora or distanceof'about three-quarters of an inch,

or more than the thickness of the plates forming the creel-boards. :In the form of top holder illustrated in Fig. 4 the thimbles, designated 16, are frictionally held in their latter frame.

interior so that they provide a long bearing 4 affording easy entrance for the tops of the skewers and the least amountof wear as the revolve therein. form, the thimble 17, forming the top holder, has theform of a rather largeeyelet, as shown in Figs. 9 and 10, which-is upset or expanded at its head within the perforation, and further held in position by meansof a bottom flange which is bent upward into engagement with the metal of the creel board. This flange may be various'ly disposed, but it is most suitably formed by reversely bending the lowerf'end of the thimble as shown at 17 until the edge thereof meets the bottom of the creel board.

The bearing thus provided for the skewer tops is devoidof cutting edges and has the flaring orifice above "mentioned, and when constructed as shown, thetop-holders do not interfere with the cleansing of the creel boards, although they, or the skewers in them, may project somewhat above the said boards. The length of the thimbles or'top holders, however, is such that a comparatively rough adjustment of the creel boards will still permit some considerable variation in the length of the different'skewers on each story, and this adjustment is facili-' tated by the fact that the creel-boards are not subject to warping, as in the case of wooden creels, and hence remain at all times substantially flat. The yarn guides 18 are carried on brackets 19 as usual, fixed to the middle creel board. Y

It is included within my invention to provide apertures or open spaces in'the creel board between the rows of skewer steps and top holders, or, if desired, to form the said In its preferred.
